Lenovo G400 Wifi
WiFi, or wireless internet, uses a piece of hardware in order to talk to your home router. Finding a WiFi adapter is easy due to the fact that all you need to know beforehand is the current operating system on your laptop. It is much simpler to buy a new USB adapter and just plug it in, than to replace any built-in adapter your laptop may have. Most USB wireless adapters are plug-n-play, which just means that you only need to put the adapter into an available USB port and the OS will handle everything from there.
